A value is part of a data record. The interpretation of the value depends on the record and there is no obvious interpretation for a value by itself

A record holds a set of values. The purpose of the record is implied by its msg member. Each field in a record has a value and an int position. The combination of msg and position conveys the interpretation of that value and it is defined by the FIT protocol. At this level, no interpretation is provided

A FIT file has a header and a list of records (in reversed order)

parse fit parses the binary content fit, typically loaded from a file

read path reads a FIT file from path in the file system. The input file must not exceed max_size (100kb by default) to protect against attacks when reading user-provided files

represent FIT file as JSON. This includes decoding some common fields in "record" messages.
